Experimenting with Docker

I just started playing with Docker and kubernete. But first I played with Docker.

Docker

PROBLEM:

• Docker doesn't actually start, when going to settings it just spins.

FIX:

• Start powershell as admin. Run: & 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon

• You may need to a) uncheck Use the WSL 2 based engine, b) Apply & Restart, c) Check Use the WSL 2 based engine (select Ubuntu 20.04), d) repeat (b)

To install this try the convenience script: https://get.docker.com/.
